on the line 7-7 of Fig. 6 showing the upper in addition.

The slipper soles known ordinarily as lambs Wool satin, and the like,soles have been open to a serious defect ever since they have been onthe market. This defect is due to the fact that the threads by which theupper is attached to the sole necessarily come directly into a positionon the outer edge in which they wear. On account of this diliculty theyhave necessarily 'been made of comparatively cheap materials becausethere was no use in using the highest Be it known that I, ERNEST A.BICKFRD,

State of Massachusetts, have invented a new and usefulv Slipper-Sole, ofwhich the fol lowing is a specification.`

.v This invention relates to a slipper sole of the type which have beensold heretofore asa separate article of manufacture for the purpose ofhaving an upper applied thereto by hand.

One of the .objects of 'this invention is to provide a construction ofthis character to strengthening them at this, their weakest point. Inspite of this serious defect the Weltefl'ect is so desirable in theappearance of the sole that an important industry has most convenientway, can also be applied by-machine, so that the complete `slipper canbe sold as an article of manufacture if desired Ainstead of the separatesole, but it is to be understood that the sole itself also constitutes aseparate article of manufacture which can be sold in several years andnumerous patents have been taken out relating to the subject.

have discovered that by an extremely simple arrangement, not involvingaddi tional expense, and in fact permitting the manufacture in a moreeconomical manner by machinery, this entire away with, sothat soles maybe made of as high grade materials as can be obtained, thefsole afterthe kand there will be no necessity for the at attaqhmentt is completedwill ,show as a taching stitches to come to wear and thus SmoothiniShedWelt, H destroy the value of the high grade mate- Theinvention also hasfor an important objectthereof the provision-of means forv attachingthev upperso arranged that none of theparts. or i 'fat'erials attaching.they upa positiontol wear,

The'ilyent/ion also involvesimprovements rialsil It also possesses theadditional adin detailst construction.` as will hppear. vantagethat theupper can be attached by hereinafte x y machinery 1f desired so that.complete slipmarket manufacred entirely by machinery and having than theAprevious 'nd attached constructions. For this purpose Italie as usual asheet of leather, pasteboard, or other comparatively stiff material andcut it out to form a body portion a. This may be provided with a liningon the top surface or not as desired, but on the bottom surface ispasted or otherwise secured an Vouter covering b comprising a thin sheetof leather, the flesh side being secured to the body portionpreferablyfsothat the rain side shall constitute the Wearing surace.
